Senior Software Engineer

Join Kargo, a leading AdTech company, as a Senior Software Engineer. In this role, you will design and build distributed services for the modernization of our Workflow Platform. You will own significant projects end-to-end, improve platform health, and mentor less experienced engineers. The ideal candidate has a strong background in software engineering, experience with distributed systems, and proficiency in modern programming languages.

• Design and build distributed services for the Workflow Platform modernization, focusing on reliability, observability, and long-term sustainability.
• Own significant projects end-to-end, from design through deployment and post-launch optimization, with minimal supervision.
• Mentor less experienced engineers and actively contribute to code reviews and design discussions, raising the quality bar for the team.

• We're looking for a self-starter who finds problems, frames them, and fixes them, and who makes the engineers around them better in the process
• B.S. or higher in Computer Science, Engineering, Mathematics, or equivalent practical experience; AdTech, programmatic, or real-time systems experience a plus
• Strong proficiency in at least one modern, high-performance language; TypeScript and/or Golang strongly preferred
• Comfortable with CI/CD pipelines, containerization (Docker, Kubernetes), cloud infrastructure (AWS, GCP, or Azure), and debugging production issues using monitoring and distributed tracing
• Solid understanding of distributed systems concepts: consistency, availability, fault tolerance, event-driven architecture, and service orchestration
• Active user of AI coding tools (Cursor, Copilot, or equivalent) with real, demonstrated productivity gains
• 5–8 years of software engineering experience, with meaningful time in distributed or high-scale backend systems
• Experience building and maintaining microservices in production at meaningful scale; async messaging (Kafka, Pub/Sub) or workflow engines a strong plus
